Description
Technical field
The utility model relates to a kind of capture device, is specifically related to a kind ofly be applied in the blast furnace hot molten slag capture device got on slag runner.
Background technology
Blast furnace hot molten slag is a kind of byproduct that ironmaking produces.Utilizing slag to prepare mineral wool at present mainly utilizes cold conditions slag as main raw material, after heating and melting and add other raw materials modified after carry out mineral wool production again; But blast furnace hot molten slag not only has very high temperature (1400 ~ 1600 DEG C), and its average heat content is about 1670MJ/t, belongs to the residual heat resources of high-quality, and also containing a large amount of mineral substance in slag; In order to make full use of the mineral in the residual heat resources of blast furnace hot molten slag and slag, be introduced directly into being in the hot blast furnace hot molten slag of industry in skull melting furnace by getting slag runner, and add the physicochemical property that a small amount of modified material (Powdered) improves slag wherein; Like this while making full use of waste residue sensible heat, also can produce mineral wool, cinder microcrystalline glass etc. and there is building material product compared with high added value.
But, due to skull melting furnace structurally, the incorporation way of especially raw material also exists huge difference with the electric smelter of inorganic materials industry.Conventional inorganic materials industry electric smelter adopts cold conditions powder to add continuously; The mode that skull melting furnace then mainly adopts blast furnace thermal slag intermittent type to add.Blast furnace hot molten slag is introduced skull melting furnace by the mode adopting intermittent type to add when utilizing blast furnace hot molten slag due to skull melting furnace, and namely blast furnace hot molten slag is by getting in the step introducing skull melting furnace of slag runner; Thus need get in slag runner arrange flashboard (gate) control blast furnace hot molten slag introduce skull melting furnace; But common flashboard (gate) is not also suitable for and gets in slag runner, and its reason is as follows:
Because blast furnace hot molten slag not only has very high temperature (1400 ~ 1600 DEG C), the flashboard thus got in slag runner needs to be cooled by water coolant usually; But so flashboard will be in cold conditions (relative to blast furnace hot molten slag); Because flashboard is in cold conditions, and between flashboard and slag runner surface, there is gap (because slag runner is inevitably existed gap by blast furnace hot molten slag corrosion etc. between reason flashboard and slag runner), this makes to infiltrate flashboard and gets, and the slag melts such as molten iron between slag runner surface are easily cooled to be solidified, flashboard and to get between slag runner surface the slag melts such as cooled molten iron and be sticked together, often easily cause flashboard to be difficult to mention by getting in slag runner, this not only causes blast furnace hot molten slag cannot introduce in skull melting furnace by getting slag runner; But also high-temperature slag spilling can be caused to get slag runner, destroy peripheral equipment, even surrounding work personnel are damaged; Thus flashboard of the prior art is difficult to be directly applied for and gets in slag runner.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of blast furnace hot molten slag capture device is provided, it ensures that flashboard can be mentioned by getting in slag runner smoothly, thus ensure that blast furnace hot molten slag can be introduced in skull melting furnace by getting slag runner smoothly, and effectively avoid high-temperature slag spilling to get slag runner, destroy peripheral equipment, even surrounding work personnel are damaged.
The technical solution of the utility model is:
